Milltek Cat Back Exhaust Volkswagen Golf Mk7.5 1.5TSI Evo GT R-Line 17-21

Milltek Cat-back Exhaust for Volkswagen Golf Mk7.5 1.5TSI Evo GT & R-Line (Both GPF/OPF & Non GPF/OPF Models) (2017-2021) – Sharper Sound, Reduced Back Pressure

This is Milltek's cat-back system for the Volkswagen Golf Mk7.5 1.5TSI Evo GT & R-Line (Both GPF/OPF & Non GPF/OPF Models). It replaces everything from the factory catalytic converter rearward with wider-bore pipework, a re-profiled mid-pipe and silencers tuned specifically for this platform, cutting back pressure and sharpening the exhaust note. The factory catalytic converter stays in place, so the car's emissions hardware is left as standard. It's offered in non-resonated, resonated EC approved or resonated versions and 11 tailpipe finishes, so you can pick the setup that suits how the car's used.

It's aimed at owners who want a noticeably different sound and a genuine, if modest, flow improvement without touching anything upstream of the cat: a straightforward bolt-on that doesn't need a remap or any other supporting mods to enjoy.

What's the difference between the resonated and non-resonated versions?

The resonated version adds extra silencing for a quieter, more refined tone. The non-resonated version leaves it out, so it is louder and more aggressive.

Which tailpipe finishes are available?

You can choose from: GT-80 Burnt Titanium, JET-90 Carbon Fibre, GT-80 Cerakote Black, GT-80 Polished, GT-80 Titanium, GT-100 Burnt Titanium, JET-102 Carbon Fibre, GT-100 Cerakote Black, GT-100 Polished, GT-100 Titanium, JET-80 Carbon Fibre. The finish is cosmetic and does not change the sound.

Yes. Milltek lists this part for the Seat Leon FR 1.8 TSI 180PS SC and 5-door as well as the other models in the fitment list above.

What is it made from?
